Hamilton County Sheriff Doug Carter is co-chairing Messer’s campaign. Former Marion County Prosecutor Scott Newman also announced his endorsement Tuesday.

Messer accepted those endorsements at a morning press conference in Fishers.

“The mantle of leadership will return to the Republican party and when it does we have to be ready. We absolutely have to be ready with a new generation of leadership that is in it for the long haul. The right kind of leadership as represented by Luke Messer,” said Newman.

Messer is one of four Republican candidates trying to unseat the longtime Republican incumbent Dan Burton.
